asked the Secretary of State for the Environment what progress is being made on the draft report relating to the operation of sanitary installations along certain stretches of trunk roads; and why this report has not yet been completed in view of the fact that the scheme was sponsored over five years ago.

The pilot scheme financed as to two-thirds by local authorities and one-third by the Government was slow to get going and the installations were not completed until 1969. A report on the experiment is still under consideration in order to decide whether the scheme should be continued and expanded.
